Life in an Ark with 50,000 others has many dangers: icebergs, unwelcome visitors, storms, woodworm and a very fragile truce between carnivores and herbivores. All hopes are pinned on a dove dispatched into the wild in search of land. The kids Finny and Leah are bored, Hazel is frustrated and Dave is worried about food supplies.

Life gets a whole lot tougher when the kids are washed overboard along with the last of the food. In a race against time, tide and a terrifying volcano, Finny must find friends, reunite family, save a colony from destruction and renegotiate a vegetarian peace deal. Oh, and has anyone seen the dove?
